Hi Venu,
it ' s hard to send you sample code. The database access is coded over more
then one class which dynamicly build sql statements. The only thing i know
is, that first a simple select is performed. After that one update on the
same table row and then a select again. Could id be that there is a lock on
this row if the statements appear to quickly? What does means "Communication
Link failure" in this context?
Thanks Uwe
